In the cold dawn of post-war Prohibition-era New York, three women find themselves inextricably tied together following a murder at the prestigious Carnival of the Seasons, a spectacle of money and magic.

For Andie Fairley, star showgirl, the Carnival is a vehicle for power. She hungers for the dangerous magic only granted to the elite. Her passionate dynamic with the young Lord Summer will either make or break her-perhaps both.

For Prue Clermont, a housewife whose marriage has been forever changed by the war, the Carnival is an escape. Yet as the lines between fantasy and reality begin to blur, Prue discovers untold horrors about the Carnival and about herself.

For Ursula Delavane, Lord Summer's domineering mother, the Carnival is a necessity. With a resistance growing, promising magic to all and not just the elite, her control is slipping. There is nothing she would not do to protect her only child.

As tensions rise and the balance of power begins to shift, whispers of prophecy and of Excalibur, the heart of all magic, are on the wind. Standing on the precipice of change, all three women must decide who they want to be, and what they're willing to sacrifice for their goals.
